The Reader Privacy Act aims to enhance privacy protections for users of book services, including both physical and electronic books. It establishes that personal information related to a user's engagement with a book service cannot be disclosed by providers or government entities, except under specific circumstances: when the user consents, when a subpoena or court order is issued, or when a government entity requires disclosure for reimbursement purposes related to educational book purchases. The bill also defines key terms such as "book," "book service," and "personal information" to clarify the scope of the law.

Additionally, the Act allows for exceptions in cases of imminent danger, where law enforcement can request personal information without a subpoena if there is a threat of death or serious injury. In such cases, the law enforcement entity must provide written confirmation of the situation within seven days. Overall, the bill seeks to align the privacy protections for book service users with existing confidentiality standards for library records, thereby safeguarding the privacy of readers and purchasers of books and e-books.
